Useful hints about ESS data

How to combine datafiles

If you want to merge data (combine variables for the same respondents) from different files of the same ESS round, you have to use the variables CNTRY (Country) and IDNO (Respondent’s identification number) as merging (“by”/”key”) variables, in that order. All files that you download from this page are sorted by CNTRY and IDNO.

Using question numbers as variable names

If you prefer to use question numbers rather than ESS variable names, you can download a program for renaming variables in spss or sas.
